Abstract
Abstract An apparatus and method for removing contamination from the body cavity of poultry includes means providing a source of pressurized water to a rotary vertical pipe having central nozzle means mounted on its upper end and to fixed side nozzles positioned adjacent opposite sides of the central nozzle with a fowl supporting and positioning rack means being positioned over the nozzles; the abdominal cavity of a fowl is positioned over the supporting and positioning rack means which is oscillated while water is ejected from the nozzles with sufficient force to remove the kidneys and contamination from the body cavity. In a second embodiment the side nozzles oscillate about the axis of the rotary vertical pipe and the supporting and positioning rack is stationary.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
82 words
A method of removing contamination from the body cavity of a fowl comprising the steps of orienting the fowl in a substantially tail-downward vertical position, positioning the fowl on a support means holding the fowl in said position, directing water jets from a plurality of relatively movable nozzles positioned in the body cavity while moving at least one group of said nozzles with respect to the fowl and creating relative movement between another group of said nozzles and the fowl supporting means.
Claim 2
Independent Claim
82 words
A method of removing contamination from the body cavity of a fowl comprising the steps of orienting the fowl in a substantially tail-downward vertical position, positioning the fowl on a support means holding the fowl in said position, directing water jets from a plurality of relatively movable nozzles positioned in the body cavity while moving at least one group of said nozzles with respect to the fowl and creating relative movement between another group of said nozzles and the fowl supporting means.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein said water is provided to said nozzles at a pressure of approximately 120 pounds per square inch.
Claim 4
Dependent Claim
40 words
The method of claim 1 wherein said relative movement between said another group of nozzles and said fowl positioning and supporting means is effected by the step of oscillating said fowl positioning and supporting means about a vertical oscillation axis.
Claim 5
Dependent Claim
23 words
The method of claim 3 wherein said water is provided to said nozzles at a pressure of approximately 120 pounds per square inch.
Claim 6
Dependent Claim
30 words
The method of claim 1 wherein said movement of said one group of nozzles is effected by rotation of said one group of nozzles about a vertical axis of rotation.
Claim 7
Dependent Claim
40 words
The method of claim 5 wherein said relative movement between said another group of nozzles and said fowl positioning and supporting means is effected by the step of oscillating said fowl positioning and supporting means about a vertical oscillation axis.
Claim 8
Dependent Claim
33 words
The method of claim 6 wherein said fowl positioning and supporting rack is oscillated about an oscillation axis that is coextensive with said vertical axis of rotation of said one group of nozzles.
Claim 9
Dependent Claim
42 words
The method of claim 1 wherein said movement of said another group of nozzle means with respect to said fowl positioning and supporting means is effected by the step of oscillating said another group of nozzle means about a vertical oscillation axis.
Claim 10
Dependent Claim
23 words
The method of claim 8 wherein said water is provided to said nozzles at a pressure of approximately 120 pounds per square inch.
Claim 11
Dependent Claim
30 words
The method of claim 8 wherein said movement of said one group of nozzles is effected by rotation of said one group of nozzles about a vertical axis of rotation.
Claim 12
Dependent Claim
32 words
The method of claim 10 wherein said another group of nozzles is oscillated about an oscillation axis that is coextensive with the vertical axis of rotation of said one group of nozzles.
